Mother Righteous (Rebecca Essex), an X-Men villain from the Krakoa era. A counterpart to Mr. Sinister and clone of the original Nathaniel Essex's wife.

I really liked her design and was a little surprised she didn't have a LoRA already. I will say that artists were not consistent with her eye color (red, blue, yellow, sometimes with yellow sclera) so I did not include a set eye color in her prompts. Be sure to pick your own if you don't want to leave it to chance.
